, MILKING-MACHINE;

To all who/m it may concern:

Be it known that I, OSCAR MonrENsnN, engineer, (who is a subject of the Kingdom of Denmark residing at Free ort, Copenhagen, Denmark, have invente useful Milking-Machine; and"1 do hereby declare the following to be a full, clear, and exact descriptionV of the same.

This invention relates toa milking machine provided with any improved form of milking cup, which surrounds the teat of the animal, which is provided with means for exerting pressure all around the teat at the root, or which exerts pressure simultaneously from two diametrically-opposite sides upon the teat, so that /cup is'olosed at its top, and the apparatus'is also provided with means for producing suction in the milking-cup, ycausing suction upon the teat;.

this s oon causes the inner elastic wall of the milklng-cup to pressontheteat, and close around this and press the Amilk out. Therepermitting the-teat to return to its natural shape, whereafter milking is kept-up, by pulsations of the apparatus, causing alternate pressure and suction.

Embodiment of the invention are shown in the accompanying drawings,wherein-- Figures l and 2 show a milking-cup in. vertical section and in elevation; Figs. 3 and-"4; show, respectively, a pulsation-valve in longitudinal section and in cross section;

fFig. 5 is a diagrammatic view of an entire apparatus embod ing the invention, including a suckingan pressingpump, asuckingyand pressingreservoir, pulsation-valves,

conducting pi es, observation.- glass and milking-cup; ig-` 6 is a vertical section of the observation-glass; Figs.- 7 and 8 show vertical sections through two-other modified constructions of 'milking-cups.

v The form of milking-cu shown in Figs` l and 2, consists of a meta -casing a having therein anlelastic-wall tubular in form, and.

secured at itsupper and lower edges only to the casing, so as to leave the thinner parts' free between said -ends; surrounding, the elastic Wall and between it and the casing, there is a hollow, elastic ring c which is fitted 'within an annular collar of the casing and is providedwith impressing-pipe The Specication of Letters YPatent.

There are' holes' 7e/ the fmetal-wall, so that the air is readily; admitted to'and egipelled from the s aeebetween the firm and the elastic wall o the milking-cup.

The milkingcup is moreover provided with eyes, (one of which is shown at 25, Fig.
